What are the possible pitfalls of making it build and then run on PPC?

I assume this means "run well in a compatible fashion on 10.4 Intel/ 
PPC, 10,5 intel/PPC as well 10.6 Intel". Perhaps obvious, but I just  
want to make it that. :-)

The problem I've had with Landon Fullers Open JDK 7 2009 beta- 
compilation – Thanks Landon! – is I'm not sure how to make it a full  
citizen. I've reset JAVA_HOME pointing to it and for some apps, like  
CLI apps, this works fine and others, like Eclipse or specifically  
Springsource Tool Suite refuse to run on it. Netbeans accepted it as a  
target VM, but I haven't been able to start up Netbeans with on it.

This leads me to the issue what distributions the Mac openJDK should  
be compatible with. Is it the openJDK on other platforms or the OS X  
java implementation style? In 10.6 it's easy to add additional JVM's,   
but seems less so in 10.5.
